sPEoIEIoATIoN forming part of Letters Patent va. 761,308, dated May 31, "1904,

Application filed November 5, 1903. Serial No. 179,968. (No model.)

To all whom it may concern.-

Be it known that I, CURTIS WALTER LESLIE, a citizen of the United States, residing at Pi ttsburg, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Trolley-Wheel Guards,

of which the following is a specification.

My invention relates to electric trolleywheel guards.

I-Ieretofore. various inventions have been produced to return the trolley to the trolleywire should it jump from the wire; and-it is to this class of devices that my invention particularly relates, my object being to providean improved and novel trolley-wheel guard of simple and comparatively inexpensive con- Struction, light, strong, and durable, and adapted to automatically return the trolley-wheel to the wire should it jump from the wire.

The invention resides in a novel manner of mounting the trolley-wheel in its head and the springs; Fig. 3, a view taken in the direction.

use of an improved spring for throwing the guard into operative position when the'trolleywheel escapes the wire and also in an improved manner of operating the guard by the trolleywheel, all as set forth in detail hereinafter and recited in the appended claims. 1

*In the accompanying drawings,Figure, -1 is a side elevation of the invention, showing the trolley-wheel on the wire; Fig. 2, a similar view showing the trolley-wheel as jumped from the wire, illustrating how the guards are automatically thrown into action by the The guard is composed of two wings 7 pivpasses through the openings 9 in both wings.

and that both wings are in substantial alinement whether folded or extended.

Numeral 12 designates the trolley-wire.

When the trolley-wheel is on the wire, the axle 3is pressed down to the bottom of slots 2 and lies in the lobes 10, as shown in Fig. 1. When thetrolley-wheel jumps the wire, as shown in Fig. 2, the springs 5 throw the axle 3 up to the upper end of slots 2, the axle 3 then passing around the pointed portions of the heart-shaped openings 9, swinging the wings 7 on the pivots 8, andfinally passing into the lobes 11, whereupon the wings 7 are in the position shown in Fig. 2, and as said wings are divergent, as shown in Fig. 3, the

guard finds the trolley-wire and directs the trolley wheel to the wire again. Immediately the trolley-wheel strikes the wire the axle 3 is pushed down in the slots 2, and the axle travels back into the lobes 10 and the wings 7 are folded, as shown in Fig. 1. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a trolley-wheel guard, the combination with a trolley-head, of a trolley-wheel movable in relation to said head, springs adapted to move the trolley-wheel, a pivoted guard having an opening provided with two lobes, and a member carried by the trolley-wheel which is received in said opening and adapted to play therein and to pass into the respective lobes when in folded and extended positions.

2. In atrolley-wheel guard,the combination with a trolley-head, of a trolley-wheel movable in relation to said head, springs adapted to move the trolley-wheel, a pivoted guard having a heart-shaped opening, and a member carried with the trolley-wheel received in said heart-shaped opening, said member being adapted to pass into one lobe of the heartshaped opening when the guard is folded and to pass into the other lobe of the heart-shaped opening when the guard is extended.

3. In a trolley-Wheel guard,the combination with a trolley-head having slots, of a trolleywheel having its axle slidable in said slots, a spring device for moving the axle in the slots, and a pivoted guard having an opening provided with two lobes, said opening receiving tenses the axle of the trolley-wheel and the lobes being adapted to respectively receive the axle when the guard is in its folded and extended positions.

4. A trolley-wheel guard comprising a trolley-head having slots, a trolley-wheel having its axle slidable in said slots, a guard comprising wings pivoted to the trolley-headand provided with heart-shaped openings receiving the axle, and a spring device for moving the axle in the slots in the trolley-head.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.
